  • the glass fibers may be used in an amount of at least, equal to, and/or between any two of 0.1 wt%, 0.2 wt%, 0.3 wt%, 0.4 wt%, 0.5 wt%, 0.6 wt%, 0.7 wt%, 0.8 wt%, 0.9 wt%, 1 wt%, 2 wt%, 3 wt%, 4 wt%, 5 wt%, 6 wt%, 7 wt%, 8 wt%, 9 wt%, 10 wt%, 11 wt%, 12 wt%, 13 wt%, 14 wt%, 15 wt%, 16 wt%, 17 wt%, 18 wt%, 19 wt%, 20 wt%, 21 wt%, 22 wt%, 23 wt%, 24 wt%, 25 wt%, 26 wt%, 27 wt%, 29
  • the low Dk and low Df glass fibers may make up all or a portion of the total short glass fibers.
  • the low Dk and low Df glass fibers may be present in the polypropylene composition in an amount of 40 wt% or less by total weight of the polypropylene composition.
  • a coupling agent may be incorporated in the polymer blend to achieve a good interface with glass fibers and the polypropylene component to enabling their uniform dispersion.
  • the coupling agent may be a maleic anhydride grafted polypropylene (MA-g-PP).
  • MA-g-PP maleic anhydride grafted polypropylene
  • the coupling occurs in situ in the extruder. With the use of this coupling agent, the interaction between the maleic anhydride group and amino group on amino-silane treated glass fibers facilitates their dispersion.
  • An example of a suitable coupling agent for polypropylene is that maleic anhydride grafted polypropylene (MA-g-PP), available as ExxelorTM PO 1020, from ExxonMobil.
  • a lubricant can be added to a polymer blend to improve the mold-making characteristics.
  • the lubricant can be a low molecular compound from a group of fatty acids, fatty acid esters, wax ester, fatty alcohol ester, amide waxes, metal carboxylate, montanic acids, montanic acid ester, or such high molecular compounds, as paraffins or polyethylene waxes.
  • the lubricant is a metal stearate.
  • metal stearates include zinc stearate, calcium stearate, lithium stearate or a combination thereof, preferably calcium stearate.
  • PC did not significantly affect the properties of the polypropylene compositions with low Dk glass fibers (compare working example WE-2 and working example WE-3), as well the polypropylene compositions with both low Dk glass fibers and glass bubbles (compare working example WE-2 and working exampleWE-4).
  • the compositions exhibited an improved metal adhesion from preliminary metal plating experiments.

Abstract

Composition de polypropylène pour utilisation dans des applications d'ondes radioélectriques haute fréquence, 6 GHz ou plus, qui comprend un mélange d'un polypropylène et de bulles de verre creuses ayant un diamètre moyen ou une granulométrie moyenne de 5 µm à 80 µm. La composition de polypropylène comprend en outre des fibres de verre présentant une longueur de 0,5 mm à 10 mm et une largeur ou un diamètre de 5 µm à 15 µm, des fibres d'oxyde d'aluminium présentant une longueur de 1 mm à 5 mm et une largeur ou un diamètre de 1 µm à 30 µm, un copolymère oléfinique cyclique et/ou un polycarbonate. La composition de polypropylène est préparée par modification d'un polypropylène par mélange à l'état fondu du polypropylène avec les différents matériaux.
